These are the two fxns
f(x) = (x+1)/(x-1)
g(x) = 1/x
I have to find f o g and f o f.
I tried to work it out but in f o g, it's too confusing what to do with the fraction in a fraction and in f o f it's in the num and denom.
I know the answers but not how to solve...
f o g = (1 + x)/ (1 - x)
f o f = X
Please help to find how to solve this! Thanks.
